Late-bound spawner for the guardian reviewer child.

The runner cannot construct a child directly: the SpawnScheduler is built after the Agent that drives the runner (a construction-order cycle), so the terminal gate spawns the reviewer through this trait object, injected per-request on AgentLoopConfig exactly like auxiliary_model_resolver. The implementation lives in the server (it captures the already-built scheduler + child-session adapter); the engine holds only the trait, keeping the engine free of any dependency on server/AppState types.

Required Methods

fn spawn_guardian_review<'life0, 'life1, 'async_trait>( &'life0 self, parent_session: &'life1 Session, review_prompt: String, model: String, disabled_tools: Option<BTreeSet<String>>, ) -> Pin<Box<dyn Future<Output = Result<String, String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Create a read-only reviewer child for parent_session_id, seeded with review_prompt, enqueue it to run, and return its session id so the caller can register a wait on it.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
